There has been a growing interest, over the past few years, in studying models of competing products/opinions on social networks. The question of interest is what is the impact of the first adopters of a product on the outcome of a series of adoption by other nodes in the system influenced by those initial nodes. More precisely, the decision of a node to adopt a product is influenced by the behaviour of its neighbours in the social network. This raises challenging and intriguing mathematical, algorithmic and game theoretic questions. In this talk, I will present an overview of recent developments in this topic.

This talk is part of the Computer Laboratory Wednesday Seminars series.
